5. © Novell Inc, Confidential & Proprietary The Storage Trends Direct Attached Storage moving to Storage Area Networks (SAN) Server Consolidation Storage Consolidation Storage Flexibility and Management LAN Free backup and archive Modern data protection (change from traditional tape backup to snap-shot, archive, geographically separated mirrored storage) Increased use of Clustering for Business Continuance solutions In light of 911, Disaster Avoidance is a key focus Clustering requires a SAN

6. © Novell Inc, Confidential & Proprietary NetWare ® Deployments 70% of NetWare new and upgrade sales are deployed on New Hardware Data growth Doubling every 12 months Digital Media is the major driving factor

7. © Novell Inc, Confidential & Proprietary Managing the Data Growth: a SAN New techniques are required in order to manage data in the future Large Data centers have figured out the value of SANs SANs help manage data Consolidate Storage Easy to provision and re-provision storage Better backup/archive SANs for Business Continuance Clustering Mirrored Geographically separate Data Centers

8. © Novell Inc, Confidential & Proprietary The SAN Problem: Costly SAN Deployment using Fibre Channel Solutions Storage Frames (FC or SCSI) ~$150,000 to $1,000,000 ea Fibre Channel Switch(s) ~$25,000 ea. Servers. HBA ~$700 ea GBIC ~$800 ea HBA=Host Bus Adapter GBIC=Gigabit Interface Converter Specialized Training $??????

9. © Novell Inc, Confidential & Proprietary The Solution: An Inexpensive SAN should: Leverage commodity Networking Hardware Leverage Local Area Networking knowledge and expertise Leverage existing networking paradigms Allow reuse of existing Direct Attached Storage hardware The Answer: iSCSI

11. © Novell Inc, Confidential & Proprietary iSCSI iSCSI is a new internet standard which defines how industry standard SCSI (Small Computer Systems Interface) storage protocols are run over industry standard TCP/IP. V1.0 was ratified on February 11, 2003 This was Internet Draft version 20 of the specification: “SCSI protocols are request/response application protocols with a common standardized architecture model and basic command set as well as standardized command sets for different device classes (disks, tapes, media-changers, etc.)” “iSCSI is a transport protocol for SCSI that works on top of TCP/IP. The iSCSI protocol aims to be fully compliant with the standardized SCSI architectural model.”

13. © Novell Inc, Confidential & Proprietary The Solution: An inexpensive SAN iSCSI on Gigabit Ethernet Hardware is a fraction of the cost of a full Fibre Channel SAN solution. Estimates are 4 to 10 times less expensive for the same amount of storage Not as performant as Fibre Channel Use existing servers as your shared storage. DAS servers converted into iSCSI Storage Arrays. No new hardware costs incurred.

Servers. Gigabit Ethernet Built-in Standard LAN infrastructure No training - $0.00 4 to 10 times less expensive than Fiber Channel

16. © Novell Inc, Confidential & Proprietary When to use iSCSI? iSCSI vs Fibre Channel is the wrong question There are no indications that iSCSI will replace Fibre Channel iSCSI will bring SANs to those who would not implement Fibre Channel iSCSI will supplement Fibre Channel for 2 nd and 3 rd tier data storage Bridged into Fibre channel Customers want to use Fibre Channel in the classic data center Already deployed Better Performance Better support from HW vendors (you get what you pay for)

17. © Novell Inc, Confidential & Proprietary When to use iSCSI? iSCSI may replace Fibre channel as data centers become more dense and iSCSI and ethernet speeds improve to beyond 1GB Blades with iSCSI Presently, customer interest and needs from iSCSI are as follows: Data migration DAS to SAN migration Site to site migration Distance replication Disaster recovery Geographic data caching Serverless backup Low cost Clusters
